A rare cardboard boxing-style concert poster advertising Sly & The Family Stone’s November, 1970 concerts at Madison Square Garden, also featuring Gladys Knight and the Pips, Rare Earth, and Sly Stone side-project 6IX.  This bold poster, measuring 14″ x 22″, is in very good+ condition with some creasing from handling, but no major issues; it will frame beautifully.  We have never seen another example of this soul classic.
